.TH SLARGV 1 "November 2006" " LAPACK auxiliary routine (version 3.1) " " LAPACK auxiliary routine (version 3.1) " .SH NAME SLARGV - a vector of real plane rotations, determined by elements of the real vectors x and y .SH SYNOPSIS .TP 19 SUBROUTINE SLARGV( N, X, INCX, Y, INCY, C, INCC ) .TP 19 .ti +4 INTEGER INCC, INCX, INCY, N .TP 19 .ti +4 REAL C( * ), X( * ), Y( * ) .SH PURPOSE SLARGV generates a vector of real plane rotations, determined by elements of the real vectors x and y. For i = 1,2,...,n ( c(i) s(i) ) ( x(i) ) = ( a(i) ) .br ( -s(i) c(i) ) ( y(i) ) = ( 0 ) .br .SH ARGUMENTS .TP 8 N (input) INTEGER The number of plane rotations to be generated. .TP 8 X (input/output) REAL array, dimension (1+(N-1)*INCX) On entry, the vector x. On exit, x(i) is overwritten by a(i), for i = 1,...,n. .TP 8 INCX (input) INTEGER The increment between elements of X. INCX > 0. .TP 8 Y (input/output) REAL array, dimension (1+(N-1)*INCY) On entry, the vector y. On exit, the sines of the plane rotations. .TP 8 INCY (input) INTEGER The increment between elements of Y. INCY > 0. .TP 8 C (output) REAL array, dimension (1+(N-1)*INCC) The cosines of the plane rotations. .TP 8 INCC (input) INTEGER The increment between elements of C. INCC > 0.
